[0037] like Figures 1 to 7 As shown, a hydrogen storage simulation module training device for fuel cell vehicles, a simulation training system, the simulation training system includes a hydrogen storage tank simulation unit, a temperature monitoring simulation unit, a pressure regulation simulation unit, a safety relief simulation unit, a gas input and output simulation unit, a central control unit and a human-computer interaction unit. By simulating a real hydrogen storage environment, the system can monitor the hydrogen storage process in real time and analyze data, ensuring that trainees fully understand and master the key operations and safety measures of hydrogen storage technology, thereby improving the safety and efficiency of actual operations;
[0038] The hydrogen storage tank simulation unit is used to simulate the actual working state of the hydrogen storage system in a fuel cell vehicle. During practical training, the hydrogen storage tank simulation unit continuously fills hydrogen to the required pressure value in the hydrogen filling state, and continuously releases hydrogen in the hydrogen discharge state, and provides real-time feedback on the status of the hydrogen tank;
[0039] The temperature monitoring simulation unit is used to maintain the temperature in the hydrogen storage tank to ensure the smooth storage and release of hydrogen. It simulates the real-time monitoring of the hydrogen temperature during hydrogenation or dehydrogenation and makes judgments on it. If the simulated temperature exceeds the limit, the temperature monitoring simulation unit triggers an emergency stop to stop the system. If the simulated temperature is within the limit, the training is carried out.
[0040] The pressure regulation simulation unit includes an outlet pipe 1, a sealing component and a trigger component. The outlet pipe 1 is installed on the hydrogen storage tank. The pressure regulation simulation unit is used to regulate the pressure in the hydrogen storage tank in real time. It simulates the real-time simulated pressure of hydrogen in the hydrogenation or dehydrogenation state and makes a judgment on it. If the simulated pressure exceeds the limit, the pressure unit triggers an emergency stop, stops the system operation and releases the pressure. If the simulated pressure does not exceed the limit, the training continues;
[0041] The safety relief simulation unit is used to automatically release pressure when the system pressure relief value exceeds the safety limit. It monitors the hydrogen pressure relief value in real time during hydrogenation or dehydrogenation and makes a judgment on it. If the simulated pressure relief value exceeds the limit, the simulation unit triggers an emergency stop, stops the system operation and releases the pressure. If the simulated pressure relief value does not exceed the limit, the training continues;
[0042] The gas input and output simulation unit is used to control the input or output of hydrogen. When simulating the hydrogenation state, the hydrogen input is controlled to simulate the filling state, and when in the hydrogenation state, the hydrogen output is controlled to simulate the hydrogenation state, so that the trainees can learn;
[0043] The central control unit is used to monitor and adjust the operating status of the entire system and, in the training simulation, to control other simulation units in real time;
[0044] The human-computer interaction unit is used to provide relevant trainees with an interface for customizing training parameters, and to control other simulation units through the central control unit, and to provide real-time feedback on relevant data of other simulation units.
[0045] The sealing component is movably arranged inside the air outlet pipe 1, and is used to release the gas when the pressure exceeds the threshold and to relieve the pressure inside the device. It includes a sealing ring 5, which is movably installed inside the air outlet pipe 1. One side of the sealing ring 5 is fixedly connected with multiple limit blocks 7, and the inner rotation of the limit block 7 is connected with a fixed block 10. The side of the fixed block 10 away from the limit block 7 is fixedly connected with a baffle 6. The outer diameter of the sealing ring 5 is consistent with the inner diameter of the air outlet pipe 1. When the gas pressure inside the device exceeds the threshold, the sealing ring 5 can move in the air outlet pipe 1 and cooperate with the starting component to quickly release excess gas to prevent the device from being subjected to excessive pressure and ensure safety. The outer diameter of the sealing ring 5 is the same as the inner diameter of the air outlet pipe 1, which ensures a good sealing effect and prevents gas leakage under normal working conditions. The limit block 7 and the fixed block 10 are The design enhances the stability of the structure, ensuring that the sealing component moves accurately when releasing pressure, and the pressure relief function will not fail due to looseness or offset. It can automatically sense and respond to changes in gas pressure without manual intervention, thereby improving the automation level and ease of operation of the equipment. During use of the device, when the gas pressure inside the device exceeds the set threshold, the sealing ring 5 begins to move along the inside of the outlet pipe 1 under the action of pressure, pushing the entire sealing component backward until it contacts the trigger component. At this time, the baffle 6 on the sealing component opens, the channel of the outlet pipe 1 is opened, and excess gas is released to the outside, thereby reducing the internal pressure and gas volume. As the internal pressure and gas volume decrease, the sealing component resets under the action of the spring 4, the baffle 6 re-closes the channel, and the device returns to a normal sealing state.
[0046] The trigger assembly is fixedly arranged inside the air outlet pipe 1, located on one side of the closing assembly, and is used to cooperate with the closing assembly to release gas and trigger the pressure relief work, including a first limiting ring 2, and a plurality of first support rods 3 are fixedly connected to the inside of the first limiting ring 2. The first support rod 3 is fixedly connected to a breakthrough body 9 on the side away from the first limiting ring 2, and a through groove is provided on the first support rod 3. The breakthrough body 9 is a cone with a sharp side close to the baffle 6 and a wide side away from the baffle 6, and a plurality of through grooves are provided in the middle of the breakthrough body 9. The breakthrough body 9 is designed as a cone structure with a sharp side and a wide side. It can accurately trigger the closing assembly when the pressure reaches the set value to achieve efficient pressure relief. The through grooves on the first support rod 3 and the through grooves in the middle of the breakthrough body 9 provide a smooth channel for gas flow, avoid blockage during pressure release, and ensure fast and efficient pressure relief. The design of the first limiting ring 2 and the first support rod 3 provides stable support for the entire trigger assembly, avoiding structural loosening or deviation during triggering. When the pressure in the vent pipe 1 is too high, the vent pipe 1 will open and the vent pipe 1 will open, and the vent pipe 1 will open, so the vent pipe 1 will open and the vent pipe 1 will open, and the vent pipe 1 will open and the vent pipe 1 will open, and the vent pipe 1 will open and the vent pipe 1 will open, and the vent pipe 1 will open and the vent pipe 1 will open, and the vent pipe 1 will open and the vent pipe 1 will open, and the vent pipe 1 will open and the vent pipe 1 will open, and the vent pipe 1 will open and the vent pipe 1 will open, and the vent pipe 1 will open and the vent pipe 1 will open, and the vent pipe 1 will open and the vent pipe 1 will open, and the vent pipe 1 will open and the vent pipe 1 will open, and the vent pipe 1 will open and the vent pipe 1 will open, and the vent pipe 1 will open and the vent pipe 1 will open, and the vent pipe 1 will open and the vent pipe 1 will open, and the vent pipe 1 will open and the vent pipe 1 will open, and the vent pipe 1 will open and the vent pipe 1 will open, and the vent pipe 1 will open and the vent pipe 1 will open, and the vent pipe 1 will open and the vent pipe 1 will open, and the vent pipe 1 will open and the vent pipe
[0047] Furthermore, as shown in Figure 3, a plurality of springs 4 are fixedly connected to one side of the first limiting ring 2, a second limiting ring 8 is fixedly connected to the side of the spring 4 away from the first limiting ring 2, and a side of the second limiting ring 8 is fixedly connected to one side of the sealing ring 5. A plurality of second support rods 12 are arranged inside the second limiting ring 8, and a third limiting ring 11 is fixedly connected to the side of the second support rod 12 away from the second limiting ring 8. The inner diameter of the third limiting ring 11 is consistent with the diameter of the widest position of the breakthrough body 9. The multi-layer limiting design of the first limiting ring 2, the second limiting ring 8 and the third limiting ring 11 ensures precise control and stability of the component during movement. The second limiting ring 8 and the sealing ring 5 are connected to each other to realize the dynamic sealing function, which not only ensures the airtightness in normal time, but also can open quickly to relieve pressure and release gas when the pressure exceeds the limit.
[0048] Further, such as Figure 2 as well as Figure 5 As shown, the baffle 6 is made of rubber, and a torsion spring (not shown in the figure) is provided at the connection between the limit block 7 and the fixed block 10. The baffle 6 made of rubber can ensure better sealing, ensuring that the device will not leak during normal use. At the same time, the reference of the torsion spring can ensure that the baffle 6 is always in a closed state during normal use.
